Vriesea plant named ‘Style’

ABSTRACT

A new and distinct  Vriesea  plant named ‘Style’ characterized as funnel form rosette plant, measuring about 45 cm in height and 35 cm to 45 cm in diameter, and produces compound, red, bipinate spike inflorescence, measuring 20 cm to 30 cm, about 2 to 6 branches, measuring about 12 cm to 17 cm in length and 3.5 cm to 5 cm in width, and green foliage, measuring 20 cm to 30 cm in length and about 4.0 cm in width.

Latin name of the genus and species of the plant claimed: Vriesea sp.

Variety denomination: ‘Style’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Vriesea plant, botanically known as Vriesea sp., hereinafter referred to by the cultivar name ‘Style’. The genus of Vriesea belongs to the Bromeliaceae family.

The new Vriesea cultivar is a product of a planned breeding program conducted by the inventors, Elly Bak and Nico D. M. Steur, in Assendelft, The Netherlands. The objective of the breeding program is to develop a new Vriesea variety good growing habit and attractive red inflorescence.

The new Vriesea cultivar ‘Style’ originated from a cross-made in a controlled breeding program by the Inventors in 1991 in Assendelft, The Netherlands. The female or seed parent is the Vriesea poelmanii cultivar designated ‘9120911’ (unpatented). The male or pollen parent is the Vriesea sp. cultivar designated ‘86395’ (unpatented). ‘Style’ was discovered and selected by the inventors in June of 1994, as a single flowering plant within the progeny of the stated cross in a controlled environment in Assendelft, The Netherlands.

Asexual reproduction of the new cultivar ‘Style’ performed by vegetative means by tissue culture was first performed in 1997, in Assendelft, The Netherlands. The first ‘Style’ plants propagated through the use of tissue culture flowered in 2002, in Assendelft, The Netherlands, and have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true-to-type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Style’ which in combination distinguish this Vriesea as a new and distinct cultivar:

-   -   1. Funnel form rosette plant, measuring about 45 cm in total         height and 35 cm to 45 cm in diameter;     -   2. Compound, red, bipinate spike inflorescence, measuring about         20 cm to 30 cm in height;     -   3. About 2 to 6 branches, measuring about 12 cm to 17 cm in         length and about 3.5 cm to 5 cm in width; and     -   4. Green foliage, measuring about 20 cm to 30 cm in length and         about 4.0 cm in width.

Plants of the parents, ‘9120911’ (unpatented) and ‘86395’ (unpatented), are no longer available to provide a botanical comparison with the new Vriesea cultivar ‘Style’. *The new cultivar ‘Style’ differs from 9120911 with a more branched inflorescence with wider branches on a shorter stem*.

Of the many commercial cultivars known to the present inventors, the most similar in comparison to the new Vriesea cultivar ‘Style’ is the Vriesea cultivar designated ‘Saturn’ (patented, EU 15605). Plants of the new cultivar ‘Style’ differ from plants of ‘Saturn’ primarily in leaf color and a more compact growth.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Vriesea cultivar ‘Style’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describes the color of ‘Style’.

The photograph shows a side view perspective of a typical potted flowering plant of ‘Style’ at about 17 months of age.

DETAILED BOTANICAL DESCRIPTION

‘Style’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, day length, fertilizers and humidity without any change in the genotype of the plant.

The aforementioned photograph, together with the following observations, measurements and values describe the new Vriesea cultivar as grown in a greenhouse in Assendelft, The Netherlands, under conditions which closely approximate those generally used in commercial practice. Plants of ‘Style’ were grown in a greenhouse with day temperatures ranging from 20° C. to 28° C. and night temperatures ranging from 18° C. to 23° C. No artificial lighting or photoperiodic treatments were conducted, but plants of ‘Style’ are forced into flowering by adding acetylene. The following fertilizer is added when growing plants of ‘Style’: 1 part nitrogen, 0.6 parts phosphor, 2 parts Kalium and 0.1 parts magnesium.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions in a greenhouse in Assendelft, The Netherlands. The age of the plants of ‘Style’ described is about 17 months.
